Carrier 58DLX07010008 Limit Switch
Limit switches are crucial due to the fact that if the air never warms up inside the exchanger then you will never get hot air through the ducts. The limit switch is a switch in the air handler that can determine when the heated air is actually warm enough for the main blower to kick in and circulate the air.
Major warnings to watch for in a failing main limit switch
- The heating and cooling system will not even start or run well like it ought to
- The Carrier system is beginning to become inconsistent occasionally
